ConclusionThe formation and diminishment of the manchette is in step with the condensation and elongation of the nucleus of the spermatid. Both the structural and positional changes of the manchette coincide with the changes of the nucleus. These results imply that manchette might play an important role in mouse spermiogenesis.

Manchette结构的形成和消失与精子细胞核的浓缩及延伸同步，其形态变化和位置改变与精子细胞核的形态学变化相吻合，在小鼠精子细胞变态成形过程中具有重要意义。

组织学结构显示长薄鳅的精巢属于小叶型，根据发育过程中细胞的大小、核仁多少、细胞核和细胞质浓缩的程度将精子发生划分为6个时相。

During spermiogenesis, the most dramatic morphological changes involve formation of the head and the flagellum, condensation of the nucleus, formation of the acrosome, and elimination of excess cytoplasm as the residual body.

成熟精子的顶体位于精子头部，内含有多种水解酶，在精子成熟、获能和受精过程中起着重要作用，因此研究顶体形成为探索控制生育和不育的机理提供了重要线索。

At last, during the incompatible interaction, chromatin condensation and marginalization in the nucleus happened, but DNA cleavage of nucleosomal and"DNA Ladder"didn't occurre.

首次利用oxyhemoglobin assay在单子叶模式植物水稻中测定了iNOS酶活性，初步明确了在Xcv与水稻细胞非亲和性互作中NO产生来源及其对过敏性反应的调控作用。

The study of the histopathology showed that the haemolymph in the disease crab decreased sharply, and was replaced by large amount of parasites, which was observed in muscle, heart and hepatopancreas from the disease crab. The pathological characteristics mainly appeared as cells swelling, necrosis, nucleus condensation and collaspe.

组织病理学观察发现，病蟹血淋巴急剧下降，代之以大量的寄生原虫，该寄生虫在病蟹的肝胰腺、鳃、心脏、肌肉等部位大量侵袭，并引起这些组织发生以坏死为主的变质性病变，其病理特征主要表现为：细胞肿胀、变性、坏死，某些细胞的细胞核固缩、碎裂或崩解。

A549 cells are more sensitive to CDDP-induced apoptosis(P.01) and less sensitive to THP andβ-Ele-induced apoptosis than A375p(P.01, P.05 respectively). Condensation and crack of nucleus and apoptotic bodies appeared in apoptotic cells of A549 and A375p cell lines in all treated groups and necrocytosis were to be seen in some groups. Fluorescence imaging experiments demonstrated that accumulation of iASPP in cytoplasm but little distribution in nucleus in all groups. untreated groups in two cell lines presented a bright-green colour,followed by CDDP-treated groups,and THP-treated groups is the darkest one in all groups.

免疫荧光显示，未加药物处理的A549和A375p细胞胞质染色均匀呈亮绿色，核区较暗；CDDP及β-Ele处理组细胞为暗绿色，其中可见皱缩的凋亡细胞；THP处理的细胞胞质荧光弱呈灰绿色，由于THP嵌入DNA自发红色荧光与二抗的绿色荧光中和，胞核被染成桔红色，结果提示药物处理后A549和A375p细胞中iASPP的表达有不同程度的下降。
